Tears of the lateral ligaments of the ankle. (a) Full thickness tear of the distal anterior talofibular ligament. There is a fluid-filled discontinuity distally (black arrow) with proximal retraction (white arrow). (b) Full thickness tear of the calcaneofibular ligament in the same patient. The ligament (white arrow) is of increased signal intensity on the proton density-weighted image and retracted posterior to the peroneal tendons. There is associated fluid in the peroneal tendon sheath (black arrow).
